There's a sharp spike & ringing on the leading edge of the square wave as it goes from the 4427 to the hexfet gate. Putting more uF across=20 the Vdd of the 4427 didn't help and there is still hissing unless one stands on the left foot with one's hand in the pocket. RF is fascinating. Let's have another go tonight. Oh by the way, am I on frequency? I miss the accurate QRG reports of Markus' OPDS. 73 Joe On Tue, 11 Nov 2014, Graham wrote: > Joe, > > Condx changed from last night ?
